One-one edge with parallelism -1 fails if source vertex parallelism is not -1 as well

// no input initializers. At this moment, only other case is 1-1 edge
// with uninitialized sources
boolean hasOneToOneUninitedSource = false;
for (Map.Entry<Vertex, Edge> entry : vertex.sourceVertices.entrySet()) {
if (entry.getValue().getEdgeProperty().getDataMovementType() ==
DataMovementType.ONE_TO_ONE) {
if (entry.getKey().getTotalTasks() == -1)

{ hasOneToOneUninitedSource = true; break; }

}
}

This checks for the source vertex which has the 1-1 edge to also have -1 parallelism.
